Therefore, for example, when the floor structure 100 is used in a hospital or a care facility, even if the patient transfers it, the influence on the patient is small. Furthermore, since the floor structure 100 includes the hollow plate 50 provided with the hollow portion 55, the floor structure 100 can have high sound insulation.

  In the floor structure 100, the base panel 42 may be a wooden plywood, and the material of the hollow plate 50 may be plastic. Therefore, in the floor structure 100, for example, compared with the case where the hollow plate 50 is wooden, it is easy to process and is lightweight. Furthermore, in the floor structure 100, compared with the case where the material of the hollow plate 50 is a metal, for example, it has high heat insulation and is lightweight.

2. Next, a floor structure 200 according to a modification of the present embodiment will be described with reference to the drawings. FIG. 3 is a cross-sectional view schematically showing the hollow plate 50 of the floor structure 200 according to a modification of the present embodiment. FIG. 4 is a plan view schematically showing the hollow plate 50 of the floor structure 200 according to a modification of the present embodiment. 3 is a cross-sectional view taken along line III-III in FIG.

  Hereinafter, in the floor structure 200 according to the modified example of the present embodiment, differences from the above-described example of the floor structure 100 according to the present embodiment will be described, and description of similar points will be omitted.

  The hollow plate 50 of the floor structure 200 is different in structure from the hollow plate 50 of the floor structure 100. As shown in FIGS. 3 and 4, the hollow plate 50 of the floor structure 200 includes a first plate-like portion 56, a second plate-like portion 57, and an uneven portion 58.

  The first plate-like portion 56 and the second plate-like portion 57 have a plate shape. The plate-like portions 56 and 57 sandwich the concavo-convex portion 58.

  The uneven portion 58 is provided between the first plate portion 56 and the second plate portion 57. The uneven portion 58 is fixed to the plate-like portions 56 and 57. The concavo-convex portion 58 has a plurality of convex portions 58a. The convex part 58a is provided periodically, for example. Therefore, the concavo-convex portion 58 has a concavo-convex shape as shown in FIG.

The convex portion 58a has a convex shape from the first plate-like portion 56 toward the second plate-like portion 57, and is connected to the second plate-like portion 57 in a region including the apex of the convex portion 58a. . A hollow portion 59 is provided between the convex portion 58 a and the first plate-like portion 56. Air exists in the hollow portion 59. In the example shown in FIG. 4, the planar shape of the convex portion 58a is a circle, and the plurality of convex portions 58a have a finely packed structure in plan view.

  In the floor structure 200, the hollow portion 55 is a region between the first plate-like portion 56 and the second plate-like portion 57 and is a region other than the uneven portion 58 and the hollow portion 59. Therefore, the hollow portion 55 communicates with the entire hollow plate 50.

  The floor structure 200 has the same effect as the floor structure 100 described above.

  In the floor structure 200, the hollow portion 55 communicates with the entire hollow plate 50. Therefore, in the floor structure 200, heat energy can be stored over the entire hollow plate 50.

  In the floor structure 200, a hollow portion 59 may be provided between the convex portion 58 a of the concavo-convex portion 58 and the first plate-like portion 56. Therefore, in the floor structure 200, heat energy can be accumulated even in the hollow portion 59.

  In the floor structure 200, the planar shape of the convex portion 58a is circular, and the plurality of convex portions 58a may have a finely packed structure in a plan view. Therefore, in the floor structure 200, for example, the compressive strength of the hollow portion 55 can be increased.

3. Experimental Example An experimental example will be shown below to explain the present invention more specifically. In addition, this invention is not limited at all by the following experiment examples.

  As an example, on a concrete slab, a 2 mm thick calp material, a 6 mm thick hollow plate (a hollow plate in which the hollow portion 55 as shown in FIG. 3 communicates with the whole), a 2 mm thick P tile. Were prepared in this order. As a comparative example, a floor structure was prepared in which P tiles with a thickness of 2 mm were directly spread on a concrete slab.

  The two rooms defined by the floor structure as described above were heated to 25 ° C and then cooled to 10 ° C. Then, both rooms were reheated by a heating device (air conditioner), and the time for the room temperature to reach 25 ° C. was measured. The air conditioner was set to 30 ° C. for heating operation, and the air volume was set to powerful operation. The thermometer was placed at a position where the wind from the air outlet of the air conditioner was not directly hit and 70 cm above the P tile.

  FIG. 3 is a graph showing the relationship between the start time of the experiment and the room temperature. The time when the thermometer reached 18 ° C. was defined as the start of the experiment (0 minutes). As shown in FIG. 3, in the comparative example, the required time to 25 ° C. was 38 minutes, whereas in the experimental example, the temperature reached 25 ° C. in 17 minutes. In the experimental example, since thermal energy was stored in the hollow portion of the hollow plate, it can be said that the temperature reached 25 ° C. 21 minutes faster than the comparative example.

  The humidity of the room at the start of the experiment (18 ° C.) was 50% in the example and 45% in the comparative example. The humidity when the temperature reached 25 ° C. was 35% in the example and 30% in the comparative example.

  The present invention includes substantially the same configuration (for example, a configuration having the same function, method, and result, or a configuration having the same purpose and effect) as the configuration described in the embodiment. In addition, the present invention includes a configuration in which non-essential portions of the configuration described in the embodiment are replaced. In addition, the present invention includes a configuration that exhibits the same operational effects as the configuration described in the embodiment or a configuration that can achieve the same object. Further, the present invention includes a configuration in which a known technique is added to the configuration described in the embodiment.
